Add image handler

[darclander]

Currently there is no solution for using .gif / .mp4 files as a moving background. Instead of only having the star-like moving background a further advancement would be to allow users to import different file-types which would be used instead as the moving background.

• Create a class image handler which will handle different filetypes.
• Allow the imported files to be transformed into a "moving background".
• Add support for .gif files
• Add support for .mp4 files

Instead of an image handler we have a videoplayer which supports "normal" videofile-formats. Gif support has not been added yet.
